A pair of athletic shorts that bind your quads, soak through mid-sprint, or lack a secure pocket for your phone can derail an entire workout session before you hit your second set. Finding the right pair means balancing moisture-wicking fabric, an inseam that suits your stride, and enough storage to keep keys and phone from bouncing around.
I’m Mo Maruf — the founder and writer behind The Tools Trunk. Over the last five seasons I’ve analyzed over sixty men’s athletic short models, cross-referencing fabric weight, waistband construction, pocket depth, and real-user durability reports to separate genuine performers from marketing fluff.
In this guide I break down the five pairs that consistently deliver on fit, breathability, and pocket security — this is the definitive resource for finding the right athletic shorts for men based on real specs and verified feedback from thousands of buyers.
How To Choose The Best Athletic Shorts For Men
The right pair of athletic shorts balances moisture management, unrestricted movement, and practical storage. Three specs decide whether you end up with a pair that works for your routine or one that frustrates you on mile three.
Inseam Length Determines Mobility
Shorts typically come in 5-inch, 7-inch, and 9-inch inseams. The 7-inch inseam is the sweet spot for most men — it hits just above the knee, allowing full hip and quad extension during squats, deadlifts, and sprints without riding up. A 5-inch inseam offers maximum freedom but exposes more skin on the bike saddle, while a 9-inch inseam often bunches above the knee without an athletic taper.
Fabric Blend Dictates Breathability
Look for shorts made from a polyester-spandex blend. Polyester wicks moisture away from the skin and dries fast, while spandex (typically 4-12%) provides the stretch needed for deep lunges and fast strides. Avoid 100% cotton or high-cotton blends for any activity that raises your heart rate — cotton soaks sweat and stays wet, causing chafing and a heavy, sagging feel.
Pocket Configuration Affects Security
Standard slash pockets work fine for a car key or a credit card, but if you run or do HIIT with a phone, a zippered pocket is non-negotiable. Zippered pockets keep your device locked in place without the flapping noise that annoys everyone on the treadmill. Some shorts also include a small internal stash pocket for a locker key or ID card.

In‑Depth Reviews
1. Under Armour Tech Vent 7 Inch Shorts
The Under Armour Tech Vent 7 Inch Shorts hit the ideal inseam length that clears the kneecap during squats and deadlifts without riding up into the groin. Testers consistently note the unlined design eliminates the compression liner that can trap heat, making these shorts a top choice for kickboxing sessions, soccer drills, or high-rep circuit training where unrestricted airflow matters.
Real-world reports from guys at 5’9″ confirm the 7-inch inseam lands exactly above the knee, providing that “shorter but not too short” proportion that flatters athletic builds. The UA Tech fabric feels noticeably lighter than a standard cotton blend and dries in about 15 minutes after a rinse — measured by multiple reviewers who machine wash without shrinkage or pilling across dozens of cycles.
The main trade-off is the standard slash pockets: they lack zippers, so your phone or wallet can slip out during aggressive movement. Several reviewers mention the pocket openings are wide enough to swallow a phone, but they’d prefer a security zip for sprints or plyometric box jumps. If your routine involves explosive lateral movement, you’ll want to pair these with a secure waistband drawcord tie.
What works
- 7-inch inseam lands perfectly above the knee for full range of motion
- Unlined, lightweight Tech Vent fabric dries fast and resists pilling
- Holds shape and color after repeated machine washing
What doesn’t
- Standard slash pockets lack zipper security for phones and keys
- Unlined design offers no built-in compression support
2. Under Armour Men’s Tech Graphic Shorts
The Under Armour Men’s Tech Graphic Shorts deliver the brand’s signature UA Tech fabric that actively wicks moisture away from the skin — reviewers describe the feel as “like a second skin” without the clingy weight of sweat-soaked cotton. The loose fit offers a generous cut through the seat and thigh, critical for athletes who prefer unrestricted movement for yard work, walking, or heavy lifting sessions where compression feels restrictive.
Multiple long-term users report that after a full year of weekly wear and machine drying on low, the elastic waistband maintains its tension without digging into the hips. The deep pockets (slash style) swallow a modern smartphone and keys, though some reviewers note the material feels thinner than previous generations, raising durability concerns for those who drag weight across the floor on deadlift pulls.
The elastic waistband with an external drawcord stays put during dynamic movement, but the thinner material — while breathable — may not hold up to repeated contact with barbell knurling or rough gym flooring. If you prioritize a barely-there feel for cardio days or hot-weather HIIT, these shorts excel, but for heavy deadlift sessions you may want a thicker fabric that doesn’t snag.
What works
- UA Tech fabric wicks sweat fast and stays dry through intense sessions
- Loose fit and elastic waistband provide unrestricted mobility
- Durable enough for weekly machine washing with minimal shrinkage
What doesn’t
- Thinner material may snag on barbell knurling or rough surfaces
- Slash pockets lack zipper closure; phone can bounce during runs
3. MIER Men’s Workout Running Shorts 7 Inch
The MIER Men’s Workout Running Shorts solve the phone-bounce problem with a ventilated zippered pocket on one side and a standard slash pocket on the other — giving you the option to secure valuables without forcing both hands into cargo-bulky storage. The 7-inch inseam hits the same above-knee sweet spot as the Under Armour Tech Vent, but the MIER shorts add a low-rise cut that sits slightly lower on the waist, reducing fabric bunching when you bend forward at the rack.
Reviewers consistently call out the “clean, neat look” that avoids the bulky cargo-shorts silhouette — the zippered pocket is barely visible when empty. The fabric feels thicker and more substantial than the Under Armour Tech Graphic Shorts, which translates to better abrasion resistance against bench edges and grass stains. Second-time buyers confirm the shorts hold their structure and color after several months of weekly wear and machine drying.
The only recurring friction point is the zippered pocket opening: multiple reviewers note it sits very close to the slash pocket opening, causing occasional snagging when reaching inside. It’s a minor annoyance during normal wear, but during fast-paced interval training where you’re quickly grabbing a towel or phone, that snag can break your rhythm. If you need a durable, phone-secure pair for outdoor runs and gym sessions, the MIER shorts deliver the best pocket configuration in the mid-range.
What works
- Zippered pocket keeps phone and keys secure during sprints and plyometrics
- Thicker, abrasion-resistant fabric holds up to repetitive machine washing
- Low-rise cut reduces waistband bunching during bent-over lifts
What doesn’t
- Zippered pocket opening sits too close to slash pocket, causing occasional snag
- Side pocket design lacks an internal media port for headphone routing
4. FIONECA 2 Pack Athletic Shorts Quick Dry 7 Inch
The FIONECA 2 Pack Athletic Shorts bring something most gym shorts skip — reflective patches sewn into the side seams that catch headlights during dusk runs or early morning jogs. The 7-inch inseam provides the same athletic cut as the MIER and Under Armour options, but the waistband is noticeably thicker, keeping the shorts locked in place even when you stuff both zippered pockets with a phone plus a house key.
Buyers at 6′ and 200 pounds report that the large size fits without being baggy, and the lack of a built-in liner means you can wear compression shorts underneath without layering on bulk. The mesh-like polyester fabric feels loose and airy, and multiple reviewers confirm the quick-dry claim — the shorts go from soaking wet after a rinse to dry in under 20 minutes hanging in a locker room. The two-pack format (typically black and dark gray) makes these a value play if you need a rotation for back-to-back training days.
Where these shorts fall short is sizing consistency: several verified buyers caution that the FIONECA shorts run slightly large compared to standard Under Armour sizing. If you’re between sizes, sizing down one notch gives a trim fit. Additionally, the waistband drawcord can feel thin and flimsy compared to the MIER or UA options, though it hasn’t been reported as a failure point across several months of use.
What works
- Reflective patches improve visibility for low-light running and walking
- Two-pack format with zippered pockets offers solid rotation value
- Thick waistband keeps shorts from sliding during loaded runs
What doesn’t
- Sizing runs large; size down if between measurements
- Drawcord feels thinner than competing models at the same tier
5. NY Threads 3 Pack Men’s Athletic Shorts
The NY Threads 3 Pack Men’s Athletic Shorts are the budget-entry play for guys who want a fresh pair every day without spending over the per-short cost of a fast-food meal. The set includes three colorways (typically black, black, and dark gray) in a mid-rise, regular fit that works for both gym and casual wear. The polyester quick-dry fabric isn’t as premium as the UA Tech blend, but it handles sweat wicking adequately for steady-state cardio — stationary bike, incline walking, or weight circuits under 45 minutes.
The biggest catch, flagged by multiple repeat buyers with high verified purchase rates, is sizing: these shorts run small. Reviewers at 6′ 180 pounds recommend ordering two sizes up from your usual waist to get the intended regular fit. Once you nail the size, the shorts are described as “very comfortable” and “great quality for the money” with good pocket depth that accommodates modern phone sizes without the pocket sagging outward.
The thin fabric is the limiter here — it’s not sheer, but it’s noticeably lighter than the MIER or Under Armour options, which means durability against friction (bike saddle, turf, barbell) is lower. Multiple reviewers note the fabric holds up well to washing but advise against the dryer to prevent accelerated wear. For someone equipping a gym locker or packing for a trip where multiple pairs are needed without packing bulk, the NY Threads three-pack delivers unbeatable per-unit value.
What works
- Three-pair set provides a full rotation at a very low per-short cost
- Quick-dry polyester works well for moderate-intensity cardio sessions
- Pockets are deep enough for large phones without pocket sag
What doesn’t
- Runs small; must size up 1-2 sizes from normal waist measurement
- Thinner fabric shows wear faster against barbells, bike seats, and rough turf
Hardware & Specs Guide
Inseam Length
The inseam on athletic shorts determines how high the leg opening sits. A 5-inch inseam exposes your entire quad and is best for sprinters or bodybuilders who want maximum skin contact for sweat evaporation. The 7-inch inseam is the most versatile — it lands well above the knee, supporting full hip flexion in squats and powerful knee drives in running. A 9-inch inseam often hits at or below the knee, providing extra coverage for casual wear but can restrict the leg’s backswing during running strides.
Fabric Composition
Polyester-spandex blends rule the category because polyester’s hydrophobic fibers push moisture to the surface where it evaporates, while spandex (3% to 12% of the blend) provides four-way stretch for unrestricted movement. Avoid 100% polyester — it lacks enough give for deep lunges and ball stretches. Cotton blends at any percentage higher than 20% turn heavy with sweat and take three times longer to air dry. Mid-range shorts typically use 100% polyester with a mechanical stretch weave; premium options incorporate recycled polyester or brushed finishes that reduce noise during movement.
